When you are configuring a Future Domain SCSI controller in Device Manager,
you may not be able to configure the controller to use the E800h-E9FFh or
EA00h-EBFFh I/O address range, even though you can configure the controller
itself to use either of these ranges. This problem is known to occur with
the following Future Domain controllers:
| • | TMC-850 |
| • | TMC-850M |
| • | TMC-850MER |
| • | TMC-850MEX |

This problem occurs because the Windows 95 SCSI.INF file and hardware
detection routine do not distinguish between the Future Domain 850- and
860-series controllers. Although the 850-series controllers can be
configured to use the I/O addresses listed above, the 860-series
controllers cannot.

The Future Domain 850-series SCSI controllers cannot be configured to use
the E800h-E9FFh or EA00h-EBFFh I/O address range when you are using the
Windows 95 protected-mode drivers. If you are using protected-mode drivers,
use one of the following valid address ranges for the controller:
| • | C800h-C9FFh |
| • | CA00h-CBFFh |
| • | CE00h-CFFFh |
| • | DE00h-DFFFh
|
If you must use the E800h-E9FFh or EA00h-EBFFh I/O address range, use the
real-mode drivers included with the controller instead of the Windows 95
protected-mode drivers.

Microsoft has confirmed this to be a problem in Microsoft Windows 95. We
are researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.
